{"product_id":"bag-end-d12e-i","title":"Bag End D12E-I Infrasub Dual 12\" Passive Install Subwoofer","description":"\u003cp\u003eThe Bag End D12E-I is a passive dual-12\" Infrasub system built for engineers and integrators who need verified low-frequency extension in permanent installations. Combining two sealed Infrasub chambers in a compact birch plywood enclosure, it is equally at home in mastering suites, post-production screening rooms, houses of worship, and high-end nightclub installs where accurate, deep bass reproduction is non-negotiable.\u003c\/p\u003e\u003cp\u003eUnlike conventional subwoofers that roll off at 20 Hz, the D12E-I achieves flat response down to 8 Hz when paired with Bag End's external Infra-MXB Integrator — a critical distinction for laboratory reference, theatrical sound reinforcement, and any application demanding true infrasonic accuracy. The integrator processes a line-level signal before the amplifier stage, allowing one or more D12E-I systems to be driven cleanly across a matched amplifier chain.\u003c\/p\u003e\u003cp\u003eFor integrators evaluating enclosure quality, the 18 mm 13-ply birch plywood construction and black Ro Tex water-borne finish signal durability without the bulk of larger competing designs. Optional fly points with a rated safe working load and an available steel yoke mount expand rigging flexibility for overhead or wall-mounted configurations, making this one of the few install subwoofers in its class that supports both surface and flown deployment.\u003c\/p\u003e","brand":"Bag End","offers":[{"title":"Default Title","offer_id":53623439327416,"sku":"207138","price":1350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/207138_Bag-End-D12E-I-Infrasub-Dual-12_-Passive-Install-Subwoofer_ALT01sqr_4f8f5f72-c04a-4ffd-8ebb-c2836f397bdf.jpg?v=1784058195","url":"https:\/\/soundpro.com\/products\/bag-end-d12e-i","provider":"SoundPro","version":"1.0","type":"link"}
